Reticulipeurus (Forcipurellus) longistylus new species
( Figs 32–39 View FIGURES 32–33 View FIGURES 34–39 , 43 View FIGURES 40–44 )
Type host. Arborophila rufogularis guttata Delacour & Jabouille, 1928 —rufous-throated partridge.
Type locality. “Indochina”.
Other hosts. Arborophila rufogularis subspecies (Blyth, 1849). Arborophila rufogularis intermedia (Blyth, 1855) . Arborophila rufogularis tickelli (Hume, 1880) .
Diagnosis. Reticulipeurus (Forcipurellus) longistylus can be separated from the other species in the subgenus by the following combination of characters: head somewhat slender ( Fig. 34 View FIGURES 34–39 ); Male pedicel swollen and shortened compared to female ( Figs 34–35 View FIGURES 34–39 ); male flagellomere I expanded distally ( Fig. 34 View FIGURES 34–39 ); male mesosome narrow ( Fig. 36 View FIGURES 34–39 ); ventral sclerite of male genitalia with narrowly rounded anterior margin ( Fig. 37 View FIGURES 34–39 ); male gonopore almost reaching distal margin of mesosome ( Fig. 37 View FIGURES 34–39 ); male parameres of distinct shape ( Fig. 38 View FIGURES 34–39 ); central section of female vulval margin more prominently bulging ( Fig. 39 View FIGURES 34–39 ); male stylus elongated and slender, not spatulate, and postero-lateral corners of male abdominal segment XI extended slightly posteriorly ( Fig. 43 View FIGURES 40–44 ).
Description. Preantennal head somewhat narrowed ( Fig. 34 View FIGURES 34–39 ). Male scape longer than female ( Fig. 35 View FIGURES 34–39 ), much wider but not otherwise modified; male pedicel short and stout; male flagellomere I with distal extension. Head chaetotaxy as in Fig. 24 View FIGURES 24–25 . Lateral margins of temples more or less parallel in male. Thoracic and abdominal segments and chaetotaxy as in Figs 32–33 View FIGURES 32–33 . Distal abdomen of male as in Fig. 43 View FIGURES 40–44 ; sternal plate VII apparently fused to from subgenital plate medianly, but this is not clear in examined specimens and plates may be separate; stylus long, elongated; distal margin of segment XI sinuously concave, lateral corners slightly extended distally. Male genitalia as in Figs 36–38 View FIGURES 34–39 . Distal rugosity of mesosome somewhat coarse, extensive. Ventral sclerite with narrowly convex anterior margin and two visible gpmes on each side. Gonopore almost reaching distal margin of mesosome. Parameres broad, curved, with elongated heads; pst1 near distal end of paramere. Female sternal plate VII without median bulge on distal margin ( Fig. 39 View FIGURES 34–39 ). Median bulge of vulval margin narrow, prominent, with 5–7 vss on each side; lateral lobes with 19–25 long, slender vms on each side. Lateral margin of claspers with 5–8 lateral setae on each side. Specimens from different host subspecies overlap extensively in vulval chaetotaxy. Measurements as in Table 1 View TABLE 1 .
Type material examined. Ex Arborophila rufogularis guttata [as A. rufogularis laotiana or A. rufogularis laotianae ]: Holotype 1♁, “ Indochina ”, 16 Jul. 1930, no collector, Brit. Mus. 1970-558, NHMUK010682710 ( NHML) . Paratypes. 1♁, skin, locality unknown, no date, coll. R . S. Balter, Brit. Mus. 1971-493, NHMUK010682705 View Materials ( NHML) .

Non-type material examined. Ex Arborophila rufogularis intermedia : 2♁, 3♀, Burma [= Myanmar], 1898, coll. R . Meinertzhagen , 3605, NHMUK010682712 View Materials ( NHML) .
Ex Arborophila rufogularis tickelli : 4♀, Tenasserim, Myanmar, Oct. 1897, coll. R . Meinertzhagen , 3601, NHMUK010682716 View Materials ( NHML) .
Etymology. The species epithet is formed by “ longus ”, Latin for “long, and “ stylus ”, Latin for “stake”, referring to the relatively long stylus of this species compared to those of other members of the subgenus.
Remarks. The type host subspecies has been selected based on the best preserved males, despite the lack of females from this host subspecies. The specimen on slide NHMUK010682704 has the same collection data as those of the holotype and may represent a female from the type host subspecies, but the subspecies is not explicit on the slide label. Specimens from the other two host subspecies are considered conspecific with the type series, as no significant differences have been found among them. Females are illustrated based on specimens from A. rufogularis intermedia .
